The value of this parameter determines how cross-reference tags are
rendered. If [tex2html_wrap6156], then the
cross-reference tag is rendered and the system continues without
waiting to check if the user wishes to follow the cross-reference.
If [tex2html_wrap6158], then AsTeR
prompts the user by playing *cross-ref-cue* (a short
sound cue) and waits for [tex2html_wrap6160] seconds before continuing. If the
user presses ``y'' in this time, the cross-referenced object is
rendered.
